Triangle $${{ABC}}$$ is rotated $${90^{\circ}}$$ clockwise around the origin.
Which of the statements below are true? Select all that apply.
a. Point $${{B'}}$$ will be located at $${(1, 4)}$$.
b. Point $${{B'}}$$ will be located at $${(4,1)}$$.
c. $$\overline{{{B'}}C'}$$ will be a vertical line.
d. $$\overline{{{B'}}C'}$$ will be parallel to $${\overline{BC}}$$.
e. The area of $$A'{{B'}}C'$$ will be greater than the area of $${{ABC}}$$, but the perimeters will be the same.
f. Both the areas and perimeters of the original and the rotated figures will be the same.
Describe how you can use transformations to show that the two figures below are congruent.
